We keep nudging pickup points when our Universal Robots UR5e setup gets unreliable at tray-to-fixture transfer with a rigid spacer block in a compact parts transfer workshop.
The tray looks like it's in the same place, but the grip seems less square. i'm suspicious of all these tweaks.
What should i inspect before blaming the arm or reteaching everything?
@RickShift Keep a copy of the current configuration and hold off on further coordinate changes. Under the appropriate isolation procedure, maintenance can use the observed rotation to focus inspection on tooling contact, mounting and tray seating.
@DanielCarter1000 The maintenance notes show contact pads were replaced before the first point adjustment. That's the first useful clue i've found in the history.
The sequence makes pad installation worth investigating, but it doesn't establish causation. Fixture variation remains a possible contributor even with that maintenance history.
Agreed, I called it too early. Treat the replacement as a lead; verify installation and contact condition alongside tray location before assigning the cause.
With multiple point changes already in our history, i'm unsure how to distinguish tooling and tray effects. How did you structure that comparison on your setup?
The original points are only a suitable reference if the confirmed tooling, frames and presentation still match. Have the responsible technician review those relationships before planning a supervised check.
